How to install bench top fume hoods properly?

Installing bench top fume hoods properly is crucial for ensuring a safe and efficient working environment in laboratories, industrial settings, and other facilities where hazardous fumes, vapors, and dusts are generated. As a trusted supplier of bench top fume hoods, we understand the importance of correct installation and are here to guide you through the process. In this blog post, we'll provide you with a comprehensive guide on how to install bench top fume hoods properly.

1. Pre - installation Preparation

Before you start the installation process, there are several important steps you need to take.

Site Assessment

First, conduct a thorough site assessment. The location where you plan to install the bench top fume hood should meet certain requirements. It should be on a stable and level surface, preferably a laboratory bench that can support the weight of the fume hood. The area should have sufficient clearance around it to allow for proper ventilation and access for maintenance. Ensure that there are no obstacles or other equipment that could obstruct the airflow or the operation of the fume hood.

Electrical and Ventilation Requirements

Check the electrical and ventilation requirements of the fume hood. Our bench top fume hoods typically require a dedicated electrical circuit to ensure safe and reliable operation. The electrical outlet should be properly grounded. Regarding ventilation, you need to have a suitable exhaust system in place. The exhaust duct should be connected to the fume hood to remove the contaminated air from the workspace. You can refer to our Duct Fume Hood page for more information on ventilation options.

Safety Precautions

Gather all the necessary safety equipment, such as safety goggles, gloves, and a dust mask. Make sure you have a clear understanding of the safety procedures associated with the installation process. Read the installation manual provided with the fume hood carefully before starting the installation.

2. Unpacking and Inspection

Once you have completed the pre - installation preparation, it's time to unpack the bench top fume hood.

Unpacking

Carefully unpack the fume hood from its packaging. Check for any visible damage during the shipping process. If you notice any dents, scratches, or broken parts, contact our customer service immediately.

Inspection

Inspect all the components of the fume hood. This includes the hood body, sashes, filters, and any other accessories. Our Fume Hood Sashes are designed to provide easy access and proper containment of fumes. Make sure all the parts are present and in good condition.

3. Installation Process

Mounting the Fume Hood

Place the fume hood on the pre - selected location on the bench. Use the mounting brackets provided to secure the fume hood to the bench. Make sure the fume hood is level and firmly attached to the bench to prevent any movement during operation.

Connecting the Electrical System

Connect the electrical wiring of the fume hood to the dedicated electrical circuit. Follow the wiring diagram in the installation manual carefully. Ensure that all the connections are tight and properly insulated to avoid any electrical hazards.

Connecting the Ventilation System

Connect the exhaust duct of the fume hood to the ventilation system. Use appropriate duct connectors and sealants to ensure an air - tight connection. This will prevent the leakage of fumes back into the workspace. The ventilation system should be able to provide the required airflow rate to effectively remove the contaminants from the fume hood.

Installing Filters

Install the filters in the fume hood according to the manufacturer's instructions. Filters play a crucial role in removing harmful particles and chemicals from the air. Different types of filters are available depending on the nature of the contaminants. Regularly replace the filters to maintain the efficiency of the fume hood.

4. Post - installation Checks

After the installation is complete, you need to perform a series of checks to ensure that the fume hood is working properly.

Airflow Testing

Use an anemometer to measure the airflow rate at the face of the fume hood. The airflow rate should meet the specified requirements in the installation manual. If the airflow rate is too low, it may indicate a problem with the ventilation system or a blockage in the duct.

Leakage Testing

Check for any air leakage around the fume hood. You can use a smoke tube or a tracer gas to detect any leaks. Seal any leaks immediately to prevent the escape of fumes.

Functionality Testing

Test all the functions of the fume hood, such as the sash movement, lighting, and fan operation. Make sure the sashes open and close smoothly, the lighting is working properly, and the fan is running at the correct speed.

5. Maintenance and Training

Proper maintenance is essential to keep the bench top fume hood in good working condition.

Maintenance

Establish a regular maintenance schedule for the fume hood. This includes cleaning the interior of the fume hood, replacing filters, and checking the electrical and ventilation systems. Regular maintenance will extend the lifespan of the fume hood and ensure its continued performance.

Training

Provide training to the users of the fume hood. They should be familiar with the proper operation, safety procedures, and maintenance requirements of the fume hood. This will help to prevent accidents and ensure the effective use of the fume hood.
